Like its simpler cousin the perpetual calendar features the custom typography by graphic designer Philippe Apeloig, one of the several details that give it a clean but nuanced look.

The new platinum model sticks to the same design, with the only tweak being the dark blue dial with silver-tone numerals and rhodium-plated hands, excepting the bright red second time zone hand at six o’clock.

Material and colour aside the watch is identical to the gold version. The case is 39.5mm in diameter, with the self-winding H1950 movement inside. It features a perpetual calendar and second time zone that can be advanced by the button at four o’clock.
